Hovedtavler

Hovedtavler, often translated as main distribution boards or main switchboards, are critical components within an electrical power system. They serve as the central point for distributing electricity from a power source, such as a utility connection or a generator, to various sub-distribution boards or directly to different circuits within a building or facility.

The primary function of a hovedtavle is to house the main incoming electrical supply and the protective devices that safeguard the entire electrical installation. This includes main circuit breakers or fuses, which are designed to interrupt the flow of current in case of overloads or short circuits, thereby preventing damage to equipment and mitigating fire hazards.

Beyond protection, hovedtavler also incorporate metering equipment to measure the total electricity consumption and may include surge protection devices to shield the system from voltage spikes. They are typically designed with robust construction to handle high current loads and ensure the reliability of the power supply. The layout and components of a hovedtavle are determined by the specific electrical demands and safety regulations applicable to the installation. Regular inspection and maintenance are essential to ensure their continued safe and efficient operation.
